The properties of magma that determines the intensity or nature of volcanic eruptions are: (1) viscosity, (2) temperature, and (3) the amount of dissolved gases. Viscosity describes the flowability of a fluid and its resistance to flow. Magma with low viscosity are more fluid-like and lets gases escape.

Answer:

Chemistry

Explanation:

The composition of magma, the temperature of magma and the amount of dissolved gasses in the magma are all responsible for the nature of eruption.

Magma could be composed of dust, blocks, bombs, cinders and other gases.

The nature of eruption also depends on the temperature as magma could erupt at varying temperatures from 700[tex]^{2}[/tex]C to 1300[tex]^{2}[/tex]C and even at higher temperatures reaching 1600[tex]^{2}[/tex]C.
